During Supersprint's long history of dyno testing, the Mercedes SL 65 AMG V12 Twin Turbo was one of the first performance cars to break the 1000 Nm torque barrier, in 2005.

While other cars made more peak Hp, at that time, the SL 65 fought them back by making monster torque in the low and mid rpm range.
In spite of those impressive numbers, we knew the some amount of performance was actually left on the table by the AMG Factory R&D Team, the culprit being the restrictive design of the stock catalysts.
As soon as we saw this, we at Supersprint immediately jumped at the opportunity of making the V12 engine even better, by improving the exhaust dynamics.
In particular, we started by designing a set of R&L, straight Turbo Downpipes, adding a larger-diameter pipe front section, and using HJS Motorsport, high-flowing cats, placing them further away from the engine.
Based upon our dyno testing, these are the real, Hp-making components of the entire exhaust.
Our Mid pipes and F1 Rear Mufflers complete the system to perfection.
This Supersprint full exhaust raises the potential of the engine to 700 + Hp, with the simple addition of a software tune.
While the performance always is our priority, we can proudly say that the sound finally becomes what the SL 65 AMG deserves, at the same time.
This Supersprint exhaust is available for the 2004-2006, original SL65 AMG, and for the facelift 2007-2011 SL 65 AMG as well.
We also offer a special version of our full D/P exhaust for the exclusive, 670 Hp limited edition SL 65 AMG "Black Series".
